Definitions

• Face masks are useful for providing protection against air pollution, as well as infectious diseases.
• Examples of face masks include disposable medical masks like the N95 mask and surgical masks, and reusable cloth masks.
• face masks can only be effective in protecting the wearers, if the wearers would keep them on their faces. It is common for wearers to remove their face masks from time to time, due to the discomfort associated with wearing face masks. It may be difficult to breathe through the face masks, especially for young children and elderly folks. Further, the face masks partially obscure the wearers’ faces, so it is difficult to recognize people when they are wearing face masks. The face masks also obscure the wearers’ facial expressions, thereby inhibiting normal social interaction.
• a face mask may include a cover shield, an input and an output fan.
• the cover shield may be shaped to cover nose and mouth of a wearer, and may define an inner space between the cover shield and the skin of the wearer.
• the input fan may be coupled to the cover shield, and may be configured to draw air from outside into the inner space.
• the output fan may be coupled to the cover shield, and may be configured to expel air out of the inner space.
